This work proposes a method for the statistical monitoring of the weekly weight of shrimp in a fish farm. The design of control charts for shrimp growth presents several challenges, the main ones being the presence of trend and autocorrelation. Several control charts are proposed, the most efficient being a chart based on the residuals of a second order autoregression whose parameters vary with the week. A control chart with less computational complexity is also provided. It is simply based on growth rates and works well at detecting negative weight changes. Real data from a large shrimp farm has been used for both the design and the evaluation.

在水产养殖中使用控制图监测虾的生长

这项工作提出了一种对养鱼场虾周重进行统计监测的方法。虾生长控制图的设计提出了几个挑战，主要是趋势和自相关的存在。提出了几种控制图，最有效的是基于二阶自回归残差的图，其参数随周变化。还提供了计算复杂度较低的控制图。它仅基于增长率，并且在检测负重量变化方面效果很好。来自大型养虾场的真实数据已用于设计和评估。
